tidemAstron: Astronomical Calculations for Tidem

Description

Do some astronomical calculations for tidem. This function is based directly on t_astron in the T_TIDE Matlab package [1].

Usage

tidemAstron(t)

Arguments

t

Either a time in POSIXct format (with "UTC" timezone), or an integer. In the second case, it is converted to a time with numberAsPOSIXct(t,tz="UTC"). If t (It is very important to use tz="GMT" in constructing t.)

Value

A list containing items named astro and ader (see T_TIDE documentation).
